Pls think n take into account these points
1).How loco change is gonna save time ??
2).Loco reversal for BBS Raj is mandatory at KGP.. earlier when GZB P4 was given from NDLS , the same loco was used up to BBS even after loco reversal at KGP and there was NO LOCO CHANGE at KGP , only reveral was done...So what diff does P7 make ?? Can't it just be used in the same way as P4 up to BBS ?? How's it gonna take more time, more manpower, more effort,...
more...

more difficulty, more hassle, more problem blah blah ?? How does it depend on loco availability if it has already a loco from GZB ?? What's the need to change it and search for other available locos ?? jst reverse it and use it... what's the big deal ??
3). And definitely P7 must be having more prestige than p4s otherwise why mostly premium trains are using it ?? And till today all Rajdhani trains are getting P7s end to end (except TVC Raj, DBRT Raj, Madgaon raj coz the entire route is not yet electrified), then why only BBS Raj must be kept out of it ??
